SigmaQuadFamily Overview
The GS81302D06/11/20/38E are built in compliance with the
SigmaQuad-II+ SRAM pinout standard for Separate I/O
synchronous SRAMs. They are 150,994,944-bit (144Mb)
SRAMs. The GS81302D06/11/20/38E SigmaQuad SRAMs
are just one element in a family of low power, low voltage
HSTL I/O SRAMs designed to operate at the speeds needed to
implement economical high performance networking systems.
Clocking and Addressing Schemes
The GS81302D06/11/20/38E SigmaQuad-II+ SRAMs are
synchronous devices. They employ two input register clock
inputs, K and K. K and K are independent single-ended clock
inputs, not differential inputs to a single differential clock input
buffer.
Each internal read and write operation in a SigmaQuad-II+ B4
RAM is four times wider than the device I/O bus. An input
data bus de-multiplexer is used to accumulate incoming data
before it is simultaneously written to the memory array. An
output data multiplexer is used to capture the data produced
from a single memory array read and then route it to the
appropriate output drivers as needed. Therefore the address
field of a SigmaQuad-II+ B4 RAM is always two address pins
less than the advertised index depth (e.g., the 16M x 8 has a
4M addressable index).
